The Corfield 66 has a focal plane shutter from 1/10 to 1/500.
It accepts 120 film in rollfilm backs, and has an interchangeable lens with a special bayonet mount, but the only lens ever made for it is the standard Corfield Lumax 95mm f/3.5. The known accessories are a grip and extension tubes, in 12mm, 24mm and 48mm lengths.

Fewer than 300 bodies were made before Corfield stopped making cameras, and eventually closed down.
